Originally posted by loyalt Back from the National meet...had a terrible time with the camera stopping mid-shoot and had to frequently turn it off and on again mid race event. I don't think it is a buffer thing, as the lens won't focus, nothing happens when pushing the shutter release button and the only way to "wake it up" was to turn off and on again. Very frustrated with this new camera having this issue all of a sudden. Lots of money and previous to this, no issues. Should I do a re-set of the camera? Is it a problem with the last firm ware update?
I'm on 1.41 since day one of release and haven't had any issues.
Here's some troubleshooting you can do to see if it's just a settings thing or if it's the camera...
For action in AF.C, set it to release priority. That way, the camera won't care if it's in focus or not.
Make sure that the AF option (viewfinder shooting) is set to "drive lens" when AF fails.
The other thing is are you bursting your shots?
Say 5 shots, track subject for a second, burst 5 more, track for a second, burst 10, etc. That will be faster than the buffer can clear so you'll hit the "buffer wall" and you'll have to wait until it clears (look at the orange led by the card door to see if it's active). If the led is active, then the camera is processing images/data (clearing the buffer). Once the led turns off, the buffer is clear for another 32 max shots or so.
